Magnetotransport and ac conductivity in 2D and 3D topological insulators — •Christian Michel and Ewelina M. Hankiewicz — Institute for Theoretical Physics and Astrophysics, University of Würzburg, D-97074 Würzburg, Germany

We study theoretically Landau level structure and optical selection rules in 2D and 3D TIs. Our focus is to find the features which are specific to the Dirac physics. We show that the optical selection rules are different for the particle-hole symmetric Dirac model in comparison with the particle-hole asymmetric models. We explain the influence of dimensionality on the characteristic features of optical selection rules.

We acknowledge grant HA 5893/4-1 within SPP 1666.
